NORTH PROVIDENCE,l .RHODE ISLAND.

Letters .Patent No. 93,971, dated August 24, 1869.

IMPRVENIBNT IN STOPPING-MECHANISM q:.EOR LOOMS.

The Schedule referred to in these Letters Patent and'makng partv of the same.

Be it known that I, G.K. DEARBORN, of Smithfield, in the county of Providence, and State of Rhode lsland, have invented certain new and useful Improvements in Stop-Motions for Looms; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing, and to the letters of reference marked thereon.

The nature of my invention consists- First, in making lthe bunter in two parts, actuated by a compound lspring or springs, the one part serving to throw oli the belt, and to :check the reacting motion of\the lay, the other part'iacting as an elastic bunter, to stop the direct motion ofthe lay.

Second, in providing the protecting-lingerswith hooked or barbed points,- so that inthe reaction of the lay these hooks will be seized upon by the lip attached to the upper part of the bunter, and checked in their motion.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and use.

Drawings.

Figure l is a perspective view, showing the frame of a loom, with the lay and my improved stop-motion attached.

Figure 2 shows, in au enlarged section, my stopping-device. y

vFigure 3 shows, in plan, the plate that holds the belt-shipping lever.

.N'N is' the lay, operating in the usual manner, and provided with the usual shuttle-slide or hatten, l?, and shuttle-boxes, L L. v

The bent lever A A is pivoted upon the protectingrod K, as shown, the end A resting upon and moving with the shuttle-binder M, which, when the shuttle is not in place, projects into the shuttlebox, as shown, and allows the lower end A of the lever to occupy the position shown in iig. 2. v

1f the lay moves up, with the lever in this position, the end A would come in contact with the stoppingdevice E B, and the loom would be at once stopped.

In case the shuttle goes .l1ome, then M will be pressed outwardly, thus throwing upward the lever A, so that, in the motion of -the lay, it will go above and clear from the stopping-device.

F is a casting, made secure to the frame of the loom, andserves as afbase, to which I attach the parts of my stopping-device.

B is a jaw, pivoted at C, and provided with an arm, D, so arranged, in connection with the belt-shipping lever Gr, that when the jaw B is thrown up, the arm D, fig. 2, presses against the lever G,'and, throwing it out of the notch h', fig. 3, allows it to spring back, and thus move the shipper O, which, throwing the belt on to the idler, stops the loom.

.As the finger A passes under the end of vB B' of the jaw, it strikes the spring-bunter E, which checks the motion ofthe lay, and causes a reaction, which, in its turn, is checked by the hook B', which seizes the finger A and holds it.

The jaw B B is hung on the pivot C, which plays in the slot T, lig. 2, thus allowing it toyield somewhat to the reactive motion of the'lay.

'lhe spring S is bent and arranged as shown in the drawings, one end acting'pon the bunter E, to press it forward; another part, pressing against O, serves to hold the leve;` B D, while the upper end or horizontal part passes forward to and over the end of the hook B', thus holding it down.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent, is l l. The bent level B D, when provided with the hook B', and working in combination with the protecting-finger A, substantially as described, and for the purpose set forth.

2. The hook B of the bent lever B D, in combination with the bunter E, substantially as described, and

for the purpose set forth.

3.- The compound spring S, acting in combination `with the bunter E, and bent lever B D, substantially as described, and for the purpose set forth.

G. K. DEARBORN.
